Rhodolite and Bertrandite Chemical Formula
While comparing Rhodolite and Bertrandite physical properties, the important data you should know is its chemical composition. Since chemical formula defines the molecular structure of the crystal, most of the physical properties like color, tenacity, solubility are governed by Rhodolite and Bertrandite chemical formula.
- Chemical formula of Rhodolite- (Mg,Fe)3Al2Si3O12
- Chemical formula of Bertrandite- Be 4Si 2O 7(OH) 2Anthony et al , Handbook of mineralogy (2001)
Rhodolite and Bertrandite Specific Gravity
Another important criteria for qualitative analysis of gemstones is Rhodolite and Bertrandite Specific gravity. Specific gravity is the relative density of a gemstone compared with respect to density of water. Gemologists use Rhodolite and Bertrandite Optical Properties during the identification of gemstone. Specific gravity of Rhodolite is 2.59-2.60 whereas that of Bertrandite is 2.59-2.60.
